Application filed March 31, 1910. Serial No. 552,663. To all whom '15 may concern Y Be 1t known that I, FRANK W. SEVERIN, a

whicha packing ring 13 is interposed. The resident of Chicago, in the county of Cook inductlon pipe exten s through the cylinderwall and its inner end disposed in the and State of Illinois, have invented certain combust1on-chamber,f so that it Will be new and useful Improvementswin Inspiraheated by the walls around the chamber tors, of which the following 1s a full, clear, and by the heat resulting from oomand exact description.

The invention relates to inspirators for internal combustion engines and by which the liquid fuel is supplied to the combustion chamber. In forcing liquid fuel into the combustion chamber of an engine, when a nozzle with a small hole is used, carbon due to theheatin a e pump, to and throu h the inductionpipe. -The inner end ofy tie inductionipe through which the fuel is discharged into t e combustion-chamber,

bustion chamber,

pipe and is normally held in` position to close valve 17, by a spring 19 disposed in the coupling 14 bet-Ween the inner end of the and a washer 20 which is `combustion chamber, so that it will be heated and discharged in thin films, without causing carbon to form in the passages for the liquid-fuel, and to effect l a tiorough vaporization of the liquid in the combustion chamber, and also to provide means which will not affect the lthe inspirator ifany carbon stem'. he pressure of the liquid fuel from the supply pipe 15 is suiiicient to overcome the force ofy spring valve 17 will be opened and the liquid passing' through the induction-pipe wlll be injected into the combustion-chamber. Stem 18 fits snugly in the bore of the inductionpipe and hasafseries of small lon itudinally extending grooves 22 in its perip ery which forms a number of small passages or ducts through which the liquid-fuel must pass in transit to the discharge end of the inductionpipe so that the liquid fuel will be thoroughly heated by contactwith t-he heated pipe. Therefore, the liquid-fuel passes through the fuel is discharged.

he invention consists in lthe novel features hereinafter set forth and more particularly defined by claims at vthe conclusion hereof.

In the drawings: Figure 1 is a central seche improved inspirator, a portion of the' combustion chamber of an engine beseries of capillary streams. tion on line 3-3of Fig. 1.- tion on line l`4 of Fig. 1.

A denotes a portion of an engine-cylinder around a'combustion-chamber a ,of the type used for crude oil, in which air is previously compressed in the combustion chamber and liquid fuel is injected through the inspirator by a positively driven fuel pump. Since, however, the particular construction of the engine forms no specific part Fig. 3 is a sec- Fig. 4 isa secbecome thoroughly and iunias it is injected into vand vabustion-chamber. Adjacent the discharge terminal of the inductionpipe its bore is slightly enlarged as 23, to

-opening or annular passage around the inner ends of grooves 22.

hen the capillary streams are forced out of grooves 22, vthe flared opening between of theinven- .t e, valve seat 16 and the the oil is injected in to the combustion-cham- Which extends -casing and is secured and a gland 12 between prises an induction-pipe 10, through the engin therein by a plugll VEN N-SEVERIN MACHINE through which oil will be forced .by a suithas been the practice to inject the oil through a nozzle having one or more very small openings, but this construction resulted in a lgreat amount of carbonization in the 5 small holes and at the discharge end of the induction nozzle or pipe. In the improved inspirator embodying the present invention, this carbonization isefliciently overcome'because the oil is dischargedin thin lms at a i0 point Where carbonization or decomposition usually occurs and furthermore if any car' bon should form between the valve and seat at the end of the induction-pipe, the operation of the inspiratorwould not be materially affected because the spring would, none the less, permit the valvevto open and the divided capillary streams in the grooves 22 to beinjected in thin films bettveen the valve and its seat.v 4

A test-cock` 25 is connected to the outer end of coupling li'and is provided with a discharge nozzle 26, a port 27 and a screwvalve 28 for closing said port. This valve permits a test to be made WheneverA desired,

to ascertain the amount of oil being pumped into the inspirator.

The invention thus providesan improved inspirator in which the liquid fuel passes through the induction-pipe in a series o 30 fine capillar streams, the grooves through which the oi passes being heated, so that t e oil will be thoroughly and evenly' heated in transit through the inspirator. -The valve at the-discharge terminal of the inductionpipe through which the 'capillary streams pass deflect the divided stre-ams into films as the oil issues from the induction-pipe, so that the inner end of the capillaryl grooves or passages are protected a ainst t e forma- 40 tion of carbon such as resu ts when they are exposed to the combustion in the combustion chamber. Furthermore the `Working of the valve tends to prevent the formation of cai'- bon at the inner end of the induction pipe and to protect the grooves, and if from any cause whatsoever, carbon should form either on the valve-seat or Athe valve, the operation I of the inspirator will not be materially affected.

The inventionis not to be understood as restricted to thedetails set forth since this may be modified within the lscope ofthe appended claims without departing from the spirit and scope of the invention.

I claim as new, and desire to secure by Letters Patent is Y l. Inan inspirator, the` combination of an v induction-pipe, extendinginto the combustion-chamber of an engine, means therein for dividing liquid into capillary streams, means for forcing liquid under pressure through said capillary streams, a coupling at the outer end of said pipe, and a test-cock 2. In an inspirator, the combination of an Y induction-pipe, a stem in'said pipe, having longitudinally extending grooves therein for dividing liquid into capillary streams, a coupling at the outer end of said pipe, a pipe connected to said coupling for supplying liquid-fuel under pressure'to the induction pipe, a test cock connected tov said coupling and an automatically closing valve at the 3. In an inspirator, thecombination of an induction-pipe extending through the vvall of an internal combustion engine and into thecombustion chamber therein, a stem exelements having longitudinally extending grooves for dividing liquid fuel intocapillary streams, means for supplying liqui fuel under pressure to said pipe, va tapered valve` seat at th@ inner end of said pipe, and..85 ya valve connected to said stem and fittin on said seat, an annular space bein forme in the other of said elements to con uct the fuel from the grooves to said seat.

4. In an inspirator, the combination of an induction-pipe extending through the Wal i of an internal combustion engine and into the combustion chamber thereinJ a stem extending through said pipe, having longitudinally extending grooves for `dividing liquid/ fuel into capillary streams, fineans for supplying liquid fuel under pressure to said pipe,ra'tapered valve seat at the inner en of said pipe, and a valve connected to said stem and fitting on said seat, an annular 1`0 space being formed in the pipe adjacent the inner end of said grooves and the valve seat to conduct the fuel from the grooves-tosai seat. v FRANK W.
